Correct regexp-based solution would be

location ~* ^/(?:forum|forums|board)(?:/|$) {
rewrite ^/[^/]*/*(.*) http://forum.my_domain.com/$2 permanent;
}

But recommended way is to avoid regexp-based solutions without
real need. It's much simplier and much more scalable to write
configuration with normal static locations, i.e.

location = /forum {
rewrite ^ http://forum.my_domain.com/ permanent;
}
location /forum/ {
rewrite ^/forum/(.*) http://forum.my_domain.com/$1 permanent;
}
location = /board {
rewrite ^ http://forum.my_domain.com/ permanent;
}
location /board/ {
rewrite ^/board/(.*) http://forum.my_domain.com/$1 permanent;
}

This way you'll save yourself a headache. As a side effect - it's
faster.
